Ubisoft has today announced the second downloadable content pack for Xbox Live Arcade title Trials Evolution will be available before the apparent end of the world this December. The Riders of Doom DLC offers players a wide range of new race tracks in the new Big Sand Lands environment, plus a range of new editor objects to build your own map.

The Riders of Doom builds on the successes of Trials Evolution offering 40 new tracks set in The Big Sand Lands – a new environment inspired by the end of the world, that gamers will see build up and tear down throughout levels – and a powerful motorbike dubbed the Banshee to add to the Trials garage. The new downloadable content will also feature hundreds of new editor objects expanding the already robust level editor. Gamer’s mettle will also be put to the test in ten brand new Skill Games, including an endless series of generated extreme obstacles.

Ubisoft hasn't revealed a proper date for the DLC, however notes that it will be out before the apparent end of the world and will be selling for 400 Microsoft Points.
